PROCESS FOR THE MANUFACTURE OF PRODUCTS HAVING A VEGETABLE BASE.

No Drawing.

To all whom it may concern:

Be it known that I, HENRI SCHMIDT, chemist, a citizen of the FrenchRepublic, residing at 7 Rue du Parc, Meudon, Department of the Seine andOise, France, have invented certain new and useful Improvements inProcesses for the Manufacture of Products Having a Vegetable Base, ofwhich the following is a specification.

The present invention has for its object a method of obtaining productswhich simplify and accelerate the preparation by the public of hotbeverages, gargles, lotions and so forth with a vegetable base.

This process is broadly characterized by the fact that on the one handthe fixed substances soluble in water and on the other hand the volatilesubstances are extracted from the plant in avoiding any alteration withcare and then by the fact that these several substances are combinedwith adding sugar in such a manner as to form a thick mass which isdivided into pellets or pieces of spherical ovoid or any otherappropriate form, these pellets being then coated with a protectinglayer of sugar or other appropriate material. In order to prepare theseproducts in the first place the quantity of plants or portions of aplant corresponding to a given number of cups of tisane must be taken.The latter is prepared in the ordinary way, that is to say, by infusion,decoction or maceration in water. The liquid portion is separated byexpressing or filtering it and is placed in an evaporating apparatus in'vacuo where it is evaporated at a low temperature until an extractpresenting the consistency of a soft paste is obtained. This extract istreated with a 15 per cent. alcoholic solution, filtered in order toeliminate precipitated mucilaginous substances and again evaporated invacuo. The same quantity of plant or of parts of plant are also takenand distilled by steam in such a manner as to extract therefrom theessential oil which is carefully collected.

The soft extract obtained in the first place is mixed in a mortar withpowdered sugar in such a manner as to form a mass of pilular consistencywith which the essential oil collected in the course of the distillationis incorporated. This mass in then divided into pellets of appropriateform which are subjected to desiccation at a low temperature and thencoated with a sufliciently thick Specification of Letters Patent.

layer of sugar or any other appropriate protecting material.

The number of pellets obtained corresponds with the number of cupsdetermined in advance and merely by solution in b0iling water, each ofthese pellets gives an infusion of the plant with which the operationhas been made. Thus infusions of tea, camomile, orange, lime and soforth or 10- tions, gargles, tisanes, hot beverages or any other aqueouspreparation with a vegetable base is formed.

The operation can be carried out with a single plant or with a mixtureof several plants.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

1. Process of making extracts from vegetable substances consisting intaking vegetable substances used both for their volatile constituentsand for their constituents soluble in water, extracting the fixedsubstances with water and evaporating in oacuo to the consistency of asoft paste, treating the paste with a 15 per cent. alcoholic solutionfiltering, and again evaporating in 'vacuo, extracting the volatilesubstances, mixing sugar with the extracted fixed substances andincorporating the volatile substances therewith.

2. Process of making extracts from vegetable substances, consisting intaking vegetable substances used both for their volatile constituentsand for their constituents soluble in water, extracting the fixedsubstances with water, evaporating to the con sistency of a soft paste,treating the paste with a 15 per cent. alcoholic solution, filtering,evaporating the solution in vacuo, adding to the extract so obtainedsugar and essential oil, mixing, dividing the products into pellets,drying said pellets at a low temperature and then coating them with alayer of sugar.

3. Process of making extracts from vegetable substances consisting intaking vegetable substances used both for their volatile constituentsand for their constituents soluble in water, infusing same, separatingthe liquid, evaporating said liquid in vacuo until an extract presentingthe consistency of a soft paste is obtained, treating the paste with a15 per cent. alcoholic solution filtering, again evaporating saidpajstein vacuo,

mixing this substance with sugar and the estial oil, dividing theproducts-into pellets," drying said-pellets 'at a low-temperature,

sential oil obtained by distilling another portion of vegetablesubstances of the-same kind-as that from which the fixed substances areextracted, dividing same into pellets of various sizes and coatingthemwith sugar.

4. Process of making extracts from vegetable substances consisting intaking veger table substances used both for their volatile constituentsand for their constituents soluble in water, infusing same, separatingthe liquid, evapor-atingsaid liquid in vacuo until an extract presentingthe consistency of a soft paste is=-obtained,-treating the paste with al5 per cent.- alcoholic solution filtering again evaporating saidpastevln oacuo, mixing this substance with sugar and essenand thencoating them with a layer of sugar.
